Inter- and intra-day accuracy and precision of alectinib quantification in rat plasma
| QC | Nominal concentration (ng/mL) | Measured concentration (ng/mL; mean ± SD) |
Accuracy (%)a | Precision (RSD, %)b | |
|---|---|---|---|---|---|
| Inter-day | LLOQ | 5 | 4.87 ± 0.53 | 97.4 | 10.9 |
| LQC | 15 | 14.3 ± 1.0 | 95.6 | 7.46 | |
| MQC | 100 | 95.8 ± 6.9 | 95.8 | 7.21 | |
| HQC | 800 | 808 ± 54 | 102 | 6.66 | |
| Intra-day | LLOQ | 5 | 4.82 ± 0.53 | 96.0 | 10.5 |
| LQC | 15 | 14.7 ± 1.2 | 98.0 | 8.36 | |
| MQC | 100 | 97.0 ± 10.5 | 97.1 | 10.8 | |
| HQC | 800 | 812 ± 46 | 101 | 5.64 |
a Accuracy was calculated by measured concentration/nominal concentration × 100%
b Precision, expressed as the relative standard deviation (RSD), was calculated as the standard deviation of the concentration/mean concentration × 100%
